TIRE-HEATER.

SPECIFICATION forming part of Letters Patent N 0. 705,340, dated July 22, 1902.

Application filed March Z6, 190'2.

To @ZZ whoml it may concern.:

Be it known that I, JACOB GOGEL, a citizen of the United States, residing 'at Toledo, in' the county of Lucas and State ofOhio," have" invented certain new and useful Improvements in Tire-Heaters; and I do hereby` declare the following to be afull, clear, and eX- f act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device which is especially designed for heating tires of different diameters preparatory to setting them.l

upon the rim or telly of a wheel.

The object of my invention is to provide for economically and effectively heating tires of larger and smallerdiameters with the least possible waste of heat or fuel; and more particularly the object is to provide a conven-v ientlyreversible cover having upper and lower annular channels of different diameters adapted for confining the heat closely around tires of different diameters, therebyeconomizing fuel and obtaining improved results.

The matter constituting myinvention will be defined in the claims.

The details of construction of my improved tire-heater are illustrated in the accompany-v ing drawings, in which'- Figure l represents a vertical section of the device with parts in elevation. Fig. 2 represents a top plan View of the heater with a portion of the cover broken away. Fig. 3 represents a top plan View of the reversible cover containing the annular heating-channels.

The circular table 1, forming a heat-retain-V ing hearth, is supported on the legs 2 and .is` provided with the upwardly-turned rim or flange 3, the interior annular flangee, anda series of upwardly-projecting radial ribs 5,

which latter are suitably spaced apart and extend radially between the iianges 3 and 4.

The compartments between these flanges and radial ribs are in practice `filled with crushed coke, sand, charcoal," or any suitable refractory material for retaining the heat and giving improved results in quickly and evenly heating the tire.

The reversible cover 6 is constructed of a broad flat circular plate or ring 6, having on one side the downwardly-projecting annular central opening 13.

"'ers 2l.

serial No. 100,106. (No model.)

flanges 7 7 ,forming the larger heating-chamber 9,and `at'the other side the upwardlyprojecting annular iianges 8 8, forming the smaller heating-chamber l0. These heatingchambers are substantially U -shaped in crosssection. The cover may be strengthened by the itersectingrods or castings l1, having centrally secured thereto -the double-ended spindle or pin 12, which is adapted to enter the opening 1 3 in a bracket or spider at .the

center of the table, as shown in Fig. l. The

double-ended spindle 12 projects at each side of the cover a sufficient length to enter the One of the rods 1l projects atthe opposite edges of the cover, forming thegpivots 14, which engage with suitable eyes in the bale 15. The bale has an exten- V'sion 15a on one side to engage with a springcatchl 16, attached to the outer iiangej in the cover to hold the cover level, but which may be disengaged when the cover is to be turned over. The cover ymay be provided with a *draft-ventb'for the escape of products of combustion.

Disposedat equal distances around the table are the upwardly-projecting pipes17, connecting` below the table with the central distributing-chamber 18, withwhich connects a supply-pipe 19, having avvalve 19a for liquid or gaseous fuel. vEach of the pipes 17 is providedat its upper'end with a'swiveled horizontal pipe 20, carrying at fits outer end a suitable'burner `2l for gas or naphtha, which may within certain llimits be swung horizontally into any desired position, as described in my previous patent, No. 680,455. In the outerflanges 7 and Sof the cover are formed verticallslots, as 22, corresponding in number and arrangement with the swinging burn` The arrangement of the burners and the slots in relation to each other is such that each of the burners may be swung into and out of the slotted opening 22, so that the flame from the burner may beprojectediinto the annular heating-chamber formed by the flanged cover and the table or hearthl.- "The swiveled burners are preferably arranged at such an angle that their flames are projected substantially in a direction tangential toth'e wallsof the annular chamber and tangentially' against the tire, thus producing within the annular chamber a continuous circuit or vortex of fiame, as described in my abovementioned patent.

The operation ot' heating tires may be conducted as follows: "he tire 23 which is to be heated is placed upon the radial ribs 5 concentric with the annular flange 4 of the table. rlhe cover 6 is swung above the table and lowered into position so that the tire is inclosed in the annular chamber formed by the cover and the table. The lighted burners 2l are swung into position so that the iiames are projected through the openings 22 into the chamber and tangentially against the tire. The compartments between the flanges and radial ribs on the table being filled with crushed coke or some refractory material retains the heat, and the chamber soon becomes a hot furnace with the fiame and gases confined closely around the tire, which in a short time becomes heated to the desired temperature. The cover may now be lifted and swung out of the way without disturbing the burners, as the slotted openings 22 extend through the lower margin of the outer flanges 7 and 8. The tire may now be removed, another put in its place, and the cover lowered without rearranging the burners in case the same-sized tire has been placed upon the table. The work of heating tires can thus be rapidly conducted. Supposing that tires of the larger diameter were first heated and that it was desired to heat tires of the smaller diameter, the cover would be reversed or turned over in the bale, so as to bring the annular chamber 10 of smaller diameter downward, and then the projection l5n of the bale is engaged with a spring-catch 16 for holding the cover level. The tire being placed in position on the table, the cover is again lowered into position by engaging the projecting end of the spindle l2 with the opening 13 in the table. The burners will again be swung into the slotted openings and the heating operation allowed to proceed as above described. It will thus be seen that tires of different diameters may be economically heated within the chambers 9 and 10 of the cover when properly adjusted on the table or hearth l. No matter what the size of the tire within the limit of the table the burners maybe swung into proper operative position in the slotted openings of the flanges 7 or 8 to heat the tire.

Having described my invention, what I claim, and desire to secure by Letters Patent,

l. In a tire-heater, the combination with a table or hearth for supporting the tire, of a reversible cover having in its opposite faces annular heating-chan nels adapted for closely confining the heat around tires on the hearth, and means for heating the channels and tires, substantially as described.

2. In a tire-heater, the combination with a table or hearth for supporting the tire, of a reversible cover having in its opposite faces heating-channels of different diameters adapted for closely confining the heat around tires of dierent diameters and means for heating the tires and channels, substantially as described.

3. In a tire-heater, the combination with a table or hearth for supporting the tire, of a reversible cover having in its opposite faces annular heating-channels, a swinging bale pivotally connected with said cover and means for centering the cover and holding it in place on the hearth, substantially as described.

4. In a tire-heater, the combination with a table or hearth for supporting the tire, of a ycover having annular heating-channels and a spindle secured centrally thereto for engagement with a central opening in the table, substantially as described.

5. In a tire-heater, the combination witha table or hearth for supporting the tire, of a removable cover having annular heatingchannels of different diameters adapted for closely confining the heat around tires of different diameters and means for heating said channels, substantially as described.

(l. In a tire-heater, the combination witha table or hearth for supporting the tire and containing heat-retaining material, of a removable cover having annular heating-channels of diierent diameters adapted for closely confining the heat around tires of different diameters and means for heating said channels, substantially as described.

In testimony whereof I aiix my signature in presence of two witnesses.

JACOB GOGEL.
